DISK FIELD OR ROAD PLOW.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed October 2, 1920. Serial No. 414,265.

To all whom it may concern:

Be it known that DREW B. THOMPSON, a citizen of the United States, residing at Blakely, in the county of Early and State of Georgia, has invented certain new and useful Improvements in Disk Field or Road Flows; and he does hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to plows for heavy work such as road or hill breaking and the object of the invention is to provide a device adapted in its arrangement and combination of parts to provide the stability and balance essential in such work.

The invention consists in the novel structure, combination and arrangement of parts hereinafter more specifically described and claimed.

One sheet of drawings accompanies this specification as part thereof in which like reference characters denote like parts throughout.

Figure 1 is a plan view of the plow.

Fig. 2 is a side elevation.

Referring to the drawings, the plow consists essentiall of a heavy beam or frame member 1 having its front end cut away in a vertical plane inclined from the line of travel as at 2 to receive a suitable plate 3 carrying a stub axle 4. Upon stub axle 4 is mounted a concave cutting wheel 5 set in a plane parallel with the oblique face 2 of beam 1. Attached to either side of beam 1 back of face 2 are attached two forwardly extending arched members 66 which pass over cutting wheel 5 and unite forwardly thereof in a pull member 7 to which are attached a cutter 9 and a draw link 8. To the near member 6 is secured a bracket 10 carrying a downwardly inclined stub axle 11 adapted to carry a concave guide wheel 12 set at an inclination from the vertical to receive a horizontal thrust toward the bar 6.

At the rear of beam 1 are secured two backwardly extending bracket members 13 and 1 1 the latter on the far side being set higher on the beam than the former secured to the near side so that the concave guide wheel 16 mounted on axle 15 journaled in these brackets is also set at an inclination similar to that of guide wheel 12 and for the same purpose.

Suitable handles 17 arealso secured to the rear of beam 1 extending upwardly and backwardly as shown.

It will be noted that in the structure shown the oblique cutting wheel is mounted directly in front of the low setting heavy frame of the frame beam, cutting wheel mount and fixed cutter, so that in operation the direct pull of the tractor is supplemented by the direct momentum thrust of the lowlying frame beam. Drifting is effectively prevented by the inclined guide wheels situated fore and aft of the cutting wheel.

hat I claim is 1. A plow comprising in longitudinal alinement a beam having its forward face in a vertical plane inclined from the line of travel and provided with a stub axle, a cutting wheel mounted on the stub axle and a draw bar.

2. A plow comprising in longitudinal alinement, a heavy beam having its forward face in a vertical plane inclined from the line of travel and provided with a stub axle perpendicular to said face, a cutting wheel mounted on said axle, arched members secured to the beam back of the cutting wheel and extending forwardly over the cutting wheel to a draw bar and alined with the beam.

3. A plow comprising in longitudinal and horizontal alinement, a beam having its forward face in a vertical plane inclined from the line of travel and provided with a stub axle, a cutting wheel. mounted on said axle and a draw bar.

In testimony whereof he aflixes his signature.

DREW B. THOMPSON.
